I applied via Campus Placement and was interviewed in Mar 2023. There were 3 interview rounds.
Question was basic and was a 1d dp question. The time in which we finish matters and code clarity is also required.
To find a loop in a LinkedIn list, we can use Floyd's cycle-finding algorithm.
Floyd's algorithm uses two pointers, one moving at twice the speed of the other.
If there is a loop, the faster pointer will eventually catch up to the slower one.
We can then reset one of the pointers to the beginning and move both at the same speed.
Where they meet is the start of the loop.
A trie is a tree-like data structure used for efficient searching of words or strings.
Trie is also known as prefix tree.
Each node in the trie represents a character in the word.
The root node represents an empty string.
The children of a node represent the next character in the word.
The end of a word is marked by a special character or a boolean flag.
Trie is commonly used in autocomplete and spell checking applications.

Grinding efficiency is influenced by factors like feed rate, material properties, grinding wheel speed, and coolant usage.
Feed rate: Higher feed rates can improve efficiency but may lead to increased wear on the grinding wheel.
Material properties: Harder materials require slower grinding speeds to achieve optimal efficiency.
Grinding wheel speed: Higher speeds can increase efficiency but may also generate more heat, aff...
Grinding media can significantly impact ball mill performance by affecting grinding efficiency and wear rate.
The type of grinding media used can affect the grinding efficiency of the ball mill.
Different materials of grinding media have varying wear rates, impacting maintenance costs.
The size and shape of the grinding media can also influence the grinding process.
For example, using ceramic balls instead of steel balls c...
Slag reactivity can impact cement performance by influencing hydration reactions and strength development.
Slag reactivity refers to the ability of slag to react with water and form cementitious compounds.
Higher slag reactivity can lead to faster hydration reactions and improved early strength development.
However, excessive slag reactivity can also result in rapid setting and reduced workability of the concrete.

FGD process is feasible for reducing air pollution from power plants.
FGD (Flue Gas Desulfurization) process is used to remove sulfur dioxide from flue gases.
It is a proven technology and has been used in power plants for decades.
FGD systems can reduce sulfur dioxide emissions by up to 95%.
The feasibility of FGD process depends on various factors such as the type of fuel used, the size of the power plant, and the cost o...

CRZ Regulations are Coastal Regulation Zone Regulations that govern activities in the coastal areas of India.
CRZ Regulations were first introduced in 1991 and have been amended multiple times since then.
They aim to protect the coastal environment and restrict certain activities in the coastal areas.
The regulations classify coastal areas into different zones based on their ecological sensitivity.
Activities like construc...
Aluminium industry involves the production and processing of aluminium metal and its alloys.
Aluminium is the third most abundant element in the Earth's crust.
The industry involves mining bauxite ore, refining it into alumina, and then smelting it to produce aluminium metal.
Aluminium is used in various industries such as construction, transportation, packaging, and electronics.
The industry is highly energy-intensive and...

Alumina is obtained from bauxite through the Bayer process.
Bauxite is crushed and mixed with sodium hydroxide to form a slurry.
The slurry is heated and pressurized in a digester to dissolve the alumina content.
The resulting solution is cooled and filtered to remove impurities.
The purified solution is then heated to precipitate the alumina as a white powder.
The alumina powder is washed, dried, and calcined to produce pu...
The reaction for Al extraction from alumina involves the reduction of alumina using carbon or electrolysis.
Alumina (Al2O3) is first converted into aluminum chloride (AlCl3) by reacting with hydrochloric acid.
The aluminum chloride is then reduced to aluminum metal by either carbon reduction or electrolysis.
In carbon reduction, carbon (usually in the form of coke) is heated with the aluminum chloride to produce aluminum ...
There are four main types of cast iron: gray iron, white iron, ductile iron, and malleable iron.
Gray iron is the most common type and has excellent castability and good machinability.
White iron is very hard and brittle, often used for wear-resistant applications.
Ductile iron has high strength and ductility, making it suitable for a wide range of applications.
Malleable iron is heat-treated to improve its strength and du
